Letters Patent No. 83,816, dated November 3, 1868.

IMPROVEMENT IN MACHINE FOR SPREADING- PLASTER, LIME, 8L0.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom ct army concern:

Be it known that I, GEORGE RELYEA, of Watkins, n the county of Schuyler, and State of New York, have invented a certain new and useful Improvement in Mar chines for Spreading Plaster, Lime, Salt, and other subchine.

Figure '2, a plan of the bottom. .Figure 3, a vertical section of one of the receptacles or sifters.

Figure 4, a view showing the airaugement of the gearing and lever-work.

Figure 5, view of the cross-slats.

Like letters of reference indicate corresponding parts in all the figures.

My invention consists in the special arrangement of the machine, as hereinafier set forth, whereby either receptacle or sifter, with connecting-mechanism on one side of the machine, may be worked independently of the corresponding parts on the opposite side; and it further consists in combining, with the perforated rcceptacles or-sifters longitudinal angular bars, and ver tical division-platesinside,whereby the plaster or other substance is kept thoroiighly stirred and lightened, in condition for passing uniformly througlrthe meshes.

In the drawings, Aindicates the main frame, B B, the driving-wheels, and O 0, half axles, resting in a central bearing, a, and made first to the driving-wheels.

In the rear of the axles are mounted two revolving receptacles or Sifters D D, likewise mounted in half axles or shafts E E, with a fixed central bearing, b, in line with a, but having the outer ends or journals, d d, resting in sliding bearings g which move forward and back on rails c c. I This sliding movement is produced through the medium of connecting-rods f f, thrown by levers G G, as clearly shown in fig. 4. The pinions 2 2, on journals d d, are therefore correspondingly thrown in and out of gear with cog-wheels 1 1, fast on the driving-wheel axis.

By this construction, I divide, so to speak, the working-mechanism into two separate and distinct parts, on opposite sides of the machine, each of which is as independent in its action as if it were embodied in a machine by itself; that is, each driving-wheel, with its independent half axle, drives one of the receptacles or sifters on its half shaft, while, if desired, the opposite side may be stationary and entirely outof gear.

The especial advantage of this arrangement is,- that while the desired width of spreading-capacity is attained by the use of twosifters, at the same time, in turning a corner, the mechanism of the swing-side of the machine may be stopped, thereby making the spreading even, and preventing the wasting of mate rial. It also allows one side'to be stopped in passing waste-spots, while the other side still keeps in opera tion. It also enables meto spread a narrow line, when desired, for instance, next to a fence.

This effect is produced-'byafcompact and simple arrangement of machinery mounted in a simple frame. i

I am not aware that the mechanism of plastcr-soweis has before been thus arranged in halves, each operated throughout independent of the other, by the action of one of the (hiring-wheels, whereby a wide or narrow spread is made. Neither I aware that two sifteis or receptacles have ever before been so arranged in line that the disengagement of the gearing is produced by throwing back the outer journals while the inner ones remain fixed.

' The sifteis may be hexagonal, octagonal, or other suitable form, in cross-section, and the planes or faces of the same are made of wire cloth, perforated metal, or other material that will produce the necessary sifting-action. One or more of these planes may be made to slide out and in, to form 'a door, to insert the substance to be spread upon the soil.

Inside, I divide each receptacle into compartments, by one or more vertical division-plates, It. I also place longitudinally in these compartments, bars :2 i, situated in a circular line, intermediate with the shaft and periphery, and arranged also in an alternately angular position, as clearly shown.

By thus combining the bars with the sitters, the revolutions will keep the plaster constantly stirred up, and prevent packing, to which it is prone, by reason of its greatweight and dampness, and therefore the sifting-action will'be produced with greater ease and unifimnitytha'n "could otherwise be the case. The

alternate angular position of the bar assists .this action, by working the plaster longitudinally from one end to the other, and their location, intermediate with the periphery and shaft, allows a free passage to the meshes. At the same time the division-plates h hold the plaster properly in the seveialcompartments, and prevent a concentration to either end, which, under some circumstances, and especially on inclined soil, might be the result. V

Hinged covers H H are made to turn over and enclose the sifters on top, to shut off dust.

What I claim as my invention, and desire to secure by Letters Patent, is-- I 1. The combination, in the same machine, of two independent sets of mechanism for sifting plaster, 850., situated end to end, the said sets consisting of revolving sifters D D, with the inner ends fixed, but the outer ones resting in slide-boxes g. g, to throw out of gear, by means of connections f j, G G, and the axle of the driving-wheels,.and the shaft ofthe siiters, made in halves, the whole arranged as described, and operating. in the manner and for the purpose specified.

2. The combination, with the perforated sifters D D, of the angular bars i i anddivision-plates h h, the whole arranged as described, and operating in the manner and for the purpose specified.

' In witness whereofil have hereunto signed my name, in the presence of two subscribing witnesses.
